Will there be a "True" or "Magnetic" display option any time soon?

I notice we can choose the most convenient units for distance, temperature, or pressure but not direction. While weather stations report degrees true, magnetic is used by sailors (and probably aviators) whose compasses have to show magnetic to agree with the backup magnetic compasses. That drives the GPS user to magnetic in setup options. My problem occurs when planning a sail racing course. I must convert true direction winds to magnetic to agree with everything else when everything else uses magnetic. The conversions can be done in my head but computers are so much quicker and more accurate that the absence of a True or Magnetic direction choice is an annoying omission.
